Replaced delivery valve seals and..... W124 300D

[gihardee]

Hi guys,

I decided to replace my delivery valve seals on my 1987 300D because they were leaking and i was having a very rough idle (W124 chassis, OM603 engine).

Essentially, i opened the delivery valves, replaced the copper shim and rubber seals on all 6.

Out of curiosity, i took out the delivery valve and the pin that goes inside the delivery valve. Additionally, i decided to take a magnet and pull out the piece underneath the delivery valve ( i dont know what it is called), everything came out pretty smooth and i put everything back exactly the way it came out. (everything went back together very smoothly without forcing anything)

I fired up the car and now it's smoking like crazy to a point where my garage fills out with black smoke and i cannot see anything, the car also sounds like it is misfiring and struggles to rev up.

What could have gone wrong? I've attached a picture of all the pieces i took out. I circled a piece in red, I am wondering if this piece is supposed to be oriented in a certain way perhaps? it's got a groove on it and 2 holes ( 1 big and a smaller one) I simply took that piece out and slipped it back in the barrel..

Can anybody help!!
